Received this from mailgun:
"You are receiving this email because we have identified you as a user of Mailgun POP3/IMAP mailboxes. We've previously communicated that we will be disabling all POP3/IMAP mailboxes."<p>Obviously they (rackspace) can't give away something they would prefer to sell for $5/mo. Has anyone found a similar service that hasn't sold out yet and is not priced per mailbox?
Mailgunner here. That's actually not the reason we end of life's the product. It just wasn't very popular unfortunately. If it was, we probably would have keep it. This was actually what we thought would be one of the coolest features of mailgun, but it never took off. Sorry you won't be able to use it anymore. Obviously you were a happy user. I wish there had been more! Btw, Rackspace email is $2/box not $5. Any they have reseller plans that cut cost even more. Not free but still really cheap. Good luck with your search!
